Autodesk 15606-011408-9005 - MAP R6.3 NAMED-10U PK, Tutorials Manual, Page: 117 / 332

You must have AutoCAD Map 3D to create object data, but anyone who uses
the free Autodesk
®
Design Review software can view it. For example, a field
worker can view a DWF
™
version of a sewer map in Autodesk
®
Design Review.
To see information about a sewer pipe, the worker holds the cursor over that
pipe. The information is available without obscuring the map itself.
The drawings in this tutorial have object data tables with information already
entered. In this exercise, you use
object data (page 313) as a query condition.
In a later exercise, you use object data to create feature classes in a new data
format.
NOTE This exercise uses the Redding.dwg map you created and modified in Exercise
1: Attach source drawings (page 99).
To create a query based on object data
1 If the Redding.dwg map from the previous exercise is not still open, reopen
it.
2 In Map Explorer, under Current Drawing, right-click Current Query, and
click Define.
3 In the Define Query of Attached Drawing(s) dialog box, do the following:
■
Under Current Query, click Clear Query.
■ Under Query Type, click Data.
4 In the Data Condition dialog box, do the following:
■ Select Object Data.
■ Under Tables, select SEWER_PIPES.
■ Under Object Data Fields, select PIPESIZE.
■ In the Expression area, under Operator, select >. Under Value, enter
8.
